Frequently Asked Questions

This is an Optical (TGG Type) Isolator: Free-Space, Polarization-Dependent. It is designed for wavelength 1030nm.

The typical isolation ranges from 26 dB (for 532, 635, 650 nm) to 30 dB (for 980, 1030, 1060 nm), and the minimum isolation ranges from 23 dB (for 532, 635, 650 nm) to 25 dB (for 980, 1030, 1060 nm).

The maximum insertion loss is 0.6 dB for 532, 635, 650 nm and 0.5 dB for 780, 850, 980, 1030, 1060 nm.

The minimum extinction ratio for all wavelengths is 28 dB.

The package dimensions are Ф19xL53mm for 1030nm. Package dimensions for shorter wavelengths are smaller, e.g. OD16xL27mm for the 532nm TGG Free Space Isolator.

The operating temperature is from 10 to 50°C and the storage temperature is from 0 to 60°C.

Contact Ascentta with your custom configuration needs. Include center wavelength, Isolation and Insertion Loss requirements for bandwidth, optical power needed and if light source is pulsed, include average, peak, and time duration. Specify package requirements such as OD, L, W, H.
